dient in several preparations, particularly the 
compound decoction of guaiacum, formerly called 
“decoction of the woods;” and the compound

however, more of their efficacy from their other 
ingredients, than from the Sassafras, a principal 
part of the efficacy of which is dissipated by boil-

inflammatory stages of ophthalmia, to which its 
softness renders it extremely well suited.
